Within-population genetic structure differs between two sympatric sister-species of ectomycorrhizal fungi, Rhizopogon vinicolor and R. vesiculosus

Creator:: Dunham, Susie M., Mujic, Alija Bajro, Spatafora, Joseph W., and Kretzer, Annette M.
Abstract:: Using spatial autocorrelation analysis, we examined the within-population genetic structure of Rhizopogon vinicolor and R. vesiculosus, two hypogeous ectomycorrhizal (EM) species that are sympatric sister taxa known to differ in their clonal structure. We collected 121 sporocarps and 482 tuberculate EM of both species from a 20 ha forest stand...

Live plant imports: the major pathway for forest insect and pathogen invasions of the US

Creator:: Liebhold, Andrew M., Brockerhoff, Eckehard G., Garrett, Lynn J., Parke, Jennifer L., and Britton, Kerry O.
Abstract:: Trade in live plants has been recognized worldwide as an important invasion pathway for non-native plant pests. Such pests can have severe economic and ecological consequences. Nearly 70% of damaging forest insects and pathogens established in the US between 1860 and 2006 most likely entered on imported live plants. The...

Phylogeny and Biogeography of Primula sect. Parryi (Primulaceae)

Creator:: Kelso, Sylvia, Beardsley, Paul M., and Weitemier, Kevin
Abstract:: Primula sect. Parryi comprises five species endemic to western North America: P. parryi, P. angustifolia, P. rusbyi, P. capillaris, and P. cusickiana with four varieties. This section, derived from a clade with representatives in Asia and Europe, exemplifies a phytogeographic pattern in which a widespread species is accompanied by multiple...

A Perithecial Sordariomycete (Ascomycota, Diaporthales) from the Lower Cretaceous of Vancouver Island, British Columbia, Canada

Creator:: Bronson, Allison W., Klymiuk, Ashley A., Stockey, Ruth A., and Tomescu, Alexandru M. F.
Abstract:: A perithecial ascomycete, Spataporthe taylori gen. et sp. nov., represented by >70 sporocarps is preserved by cellular permineralization in marine carbonate concretions dated at the Valanginian-Hauterivian boundary (Early Cretaceous) from Vancouver Island, British Columbia, Canada. The spheroid perithecia with lumina 330–470 µm wide and 220–320 µm high are densely distributed...

Senftenbergia oregonensis (Arnold) comb. nov. (Filicales): Delimiting Relationships Among Paleozoic Tedeleaceae

Creator:: Hillier, Kaitlin G. and Rothwell, Gar W.
Abstract:: Reexamination of fossilized plant material from the westernmost Pennsylvanian-age wetland flora in North America reveals that material of Pecopteris oregonensis Arnold represents a filicalean fern frond with annulate sporangia and anatomically preserved vascular tissues of the rachis. The frond, which is redescribed as Senftenbergia oregonensis (Arnold) Hillier et Rothwell comb....

Comparative Genomics of a Plant-Pathogenic Fungus, Pyrenophora tritici-repentis, Reveals Transduplication and the Impact of Repeat Elements on Pathogenicity and Population Divergence

Creator:: Manning, Viola A., Pandelova, Iovanna, Dhillon, Braham, Wilhelm, Larry J., Goodwin, Stephen B., Berlin, Aaron M., Figueroa, Melania, Freitag, Michael, Hane, James K., Henrissat, Bernard, Holman, Wade H., Kodira, Chinnappa D., Martin, Joel, Oliver, Richard P., Robbertse, Barbara, Schackwitz, Wendy, Schwartz, David C., Spatafora, Joseph W., Turgeon, B. Gillian, Yandava, Chandri, Young, Sarah, Zhou, Shiguo, Zeng, Qiandong, Grigoriev, Igor V., Ma, Li-Jun, and Ciuffetti, Lynda M.
Abstract:: Pyrenophora tritici-repentis is a necrotrophic fungus causal to the disease tan spot of wheat, whose contribution to crop loss has increased significantly during the last few decades. Pathogenicity by this fungus is attributed to the production of host-selective toxins ( HST), which are recognized by their host in a genotype-specific...

Spatiotemporal Assessment of Crop Histories in the Pacific Northwest

Creator:: Kumbhakar, Ishika G.
Abstract:: The cultivated potato (Solanum tuberosum) is one of the most important food crops in the United States, as well as globally. As demand rises, growers in the Pacific Northwest are revisiting their crop management strategies to determine whether there are additional ways to enhance crop productivity while managing plant and...

Chaparral history, dynamics, and response to disturbance in southwest Oregon : insights from age structure

Creator:: Duren, Olivia
Abstract:: Fuels management on Bureau of Land Management lands in SW Oregon, USA, is motivated by the needs to reduce fire hazard and restore ecosystems thought to be impacted by fire suppression. Chaparral is one of the most characteristic vegetation communities of SW Oregon's interior valleys, and extensive acreages within this...

Fire history of the ponderosa pine forests of the Warm Springs Indian Reservation, Oregon

Creator:: Soeriaatmadja, Roehajat Emon, 1936-
Abstract:: Fire has played a prominent role in the development and character of the ponderosa pine forests in western North American. Its records are written in the scars of trees that have survived the fire. Careful studies of these fire-scars may be used as a means of reconstructing the fire history...
